MOULDED BODIES CONSISTING OF CORE-SHELL PARTICLES.

摘要

The invention relates to moulded bodies having an optical effect, essentially consisting of core-shell particles comprising a shell which forms a matrix and a core which is essentially solid and has an essentially monodisperse size distribution, the refractive index of the core material being different from that of the shell material. The invention is characterised in that at least one contrast material is stored in the matrix.
